Isotopically Engineered Diamond for Quantum Technology

Reliable supply of CVD diamond layers and tailored to need color centers for quantum technology applications is key in order to bridge the gap between laboratory research, where unique diamond samples are used to show the potential of certain technologies and commercial products where uniformly produced diamonds are used. In order to master the challenges in the individual disciplines of diamond based quantum computing and quantum sensing, customized diamond material must be produced.<br/>In particular, the generation of qubit chains, in which NV centers are coupled to ¹³C nuclear spins, is a technological challenge, as individual atomic distances have to be controlled.<br/>However, the realization of such diamond qubit chips is essential for the advancement of diamond quantum computing.<br/>The diamond material must also be pushed to the limit in the field of sensor technology. Atomically small sensor elements that are shielded from the immediate environment and surrounded by few to no defects must be produced in a repeatable and consistent quality.<br/>We at Diatope engineer these systems through the unique combination of CVD diamond growth, ion implantation and annealing and quantum characterization from a single source at a single location.
